of knowing what the body needs.
The Beginning
Where science met nutrition.
The program was born inside hospital walls — a supervised detoxification protocol designed by doctors and nutritionists for patients who needed metabolic reset under medical care. Controlled, measured, effective.
The Expansion
Clinical rigor, beautiful setting.
The program moved into hotel wellness centers across Serbia and the region. Clients could experience the full five-day protocol in a retreat setting — with the same medical oversight, but surrounded by comfort instead of clinical walls.
2020
The world changed. We adapted.
When the pandemic made retreats impossible, the team engineered a home delivery system that preserved the nutritional precision and daily structure of the original protocol. Thousands of clients across four countries proved it worked.
2026
Nearly twenty years in the making.
WAGA Wellness brings the full program to New York City — the same clinical foundation, the same team oversight, the same five-day arc. Adapted for the city. Delivered to your door.
Where It Began
Between clinical precision and everyday life.
Nadja Radonjić spent years working inside retreat detox programs — environments where every meal was measured, every outcome tracked, and every patient monitored by a medical team. The results were remarkable. But they ended at the retreat door.
Patients would return to their lives and, within weeks, lose everything they had gained. The problem was never willpower. It was infrastructure. There was no bridge between clinical-grade nutrition and the reality of a busy life. Nadja set out to build one.
Not a metaphor. A clinical reality. Every meal in the program is calibrated to trigger specific physiological responses — not just to nourish, but to heal.
Given the right inputs, your body will do the work. We don't force outcomes — we create the conditions for your system to restore itself.
Fewer decisions, fewer ingredients, fewer distractions. The power of the program is in its constraint. Five days. Complete focus. Nothing extra.
The Team
Credentials you can verify. Expertise you can feel.
